Ive done what you said but it didn’t have the result i expected. it gave a grey screen,

here I’ve pasted my patch with camera capture set to 0 so you can see what I’ve got going on,
It is the world i am trying to attach the cornerpin to, to map it onto a real object.
Hope you can help me out!
Best

ok, in this case it’s probably better to use jit.gl.node.
simply add all your opengl objects to the jit.gl.node sub-context (by conntecting the middle outlet, or by providing the sub-context name to as the first argument to your opengl object).
then enable capturing on the gl.node, and send to the cornerpin.
